P-type atpase是什么
WebP-type ATPases catalyze the selective active transport of ions like H+, Na+, K+, Ca2+, Zn2+, and Cu2+ across diverse biological membrane systems. Many members of the P-type ATPase protein family, such as the Na+,K+-, H+,K+-, Ca2+-, and H+-ATPases, are involved in the development of pathophysiological conditions or provide critical function to ... WebJul 9, 2009 · The unique status of this P-type ATPase is further underlined by the presence of two additional subunits, namely KdpF (3 kDa) and KdpC (20 kDa). Whereas the former is thought to be of structural importance for the integrity of the enzyme complex, the latter is most likely involved in catalysis. In this review, these rather unique features of ...
